ZEFIROEnglish• Now point the gun at the solvent tank and press the triggerso as to recover the residual solvent.• As the pump starts idling, press the switch (H2) OFF (0)to stop the equipment.H2ALWAYS DISCONNECT THE POWER SUPPLYAND RELEASE THE PRESSURE IN THE PUMPINGGROUP (open the drain valve) BEFORE TIGHTE-NING THE PACKING NUT.OFFOil ringI1Ref. 11503• Use the lubricant (I2) supplied (rif. 16325) to allow an easysliding of the piston inside the gasket group.Daily top up the packing nut.H2I2Ref. 16325• In case of long storage, we recommend you to suck andto leave light mineral oil inside the pumping group and theflexible hose.Follow the washing procedure before using againthe equipment.IROUTINE MAINTENANCECHECK ON THE PACKING NUTDaily check the packing nut is tight in order to avoid wastes butnot excessively to prevent the piston from seizing and thegaskets from wearing.• For tightening, use the wrench (I1) supplied (ref. 11503).18
L PROBLEMS AND SOLUTIONSZEFIROProblem• The equipment does not start• Lack of voltage;Cause• Considerable drops in mains voltage;• On/Off switch disconnected;• Breakdown of pressure transmitter;• Breakdown of motor electric control box;• The line of material coming out of thepump is already under pressure;• The product is solidified inside thepump;Solution• Check the correct connection to thepower supply;• Check the extension cable;• Ensure the On/Off switch is on the“on” position and turn clockwise thepressure control knob;• Verify and replace it, if necessary;• Verify and replace it, if necessary;• Open the drain valve to releasepressure in the circuit;• Open the drain valve to releasepressure in the circuit and stop themachine. Disassemble the pumpinggroup and the pressure transmitterand clean;English• The equipment does not suck theproduct• Suction filter clogged;• Suction ilter too fine;• The equipment sucks air;• Clean or replace it;• Replace it with a larger-mesh filter(with very dense products, removethe filter);• Check the suction pipe;• The equipment sucks but does notreach the pressure desired• Lack of product;• The equipment sucks air;• The drain valve is open;• The gaskets of the pumping group areworn;• Suction or delivery valve dirty;• Add the product;• Check the suction pipe;• Close the drain valve;• Replace the gaskets;• Disassemble the pumping group;• When pressing the trigger, thepressure lowers considerably• Nozzle too big or worn;• The product is too dense;• The filter of the gun-butt is too fine;• Replace it with a smaller one;• Dilute the product, if possible;• Replace it with a larger-mesh filter;• The pressure is normal but theproduct is not atomized• The nozzle is partially clogged;• The product is too dense;• The filter of the gun-butt is too fine;• Clean or replace it;• Dilute the product, if possible;• Replace it with a larger-mesh filter;• The atomization is imperfect• The nozzle is worn;• Replace it;• When releasing the trigger of thegun, the equipment does not stop(the motor runs slowly and thepiston rod keeps on going up anddown)• The gaskets of the pumping group areworn;• Suction or delivery valve dirty;• Drain valve defective;• Replace the gaskets;• Disassemble the pumping group andclean;• Verify and replace it, if necessary;Always close the air compressed supply and unload the plant pressure before performing any check or replacementof pump parts (see "correct procedure of decompression").19
